IAN Holloway has been hugely impressed with newly-promoted Brentford – saying their performance against Nottingham Forest in midweek was a "joy to watch".
The Bees travel to The Den on Saturday on the back of an impressive 3-1 victory at the City Ground on Wednesday.
And having reviewed the match, Holloway believes Brentford will be the toughest opponent Millwall have faced so far this season.
He said of Mark Warburton's side: "I'm so impressed with Brentford and the way they play.
"They have got their own identiy so well done to them. They lost their manager [Uwe Rosler] last year but Mark (pictured) has taken them forward a step.
"They were absolutely brilliant against Forest – a joy to watch. They are going to be the toughest opponent we've faced because they have a fantastic way of playing.
"I'm all excited because I cannot wait to try and stop them and impose our game on theirs. It's going to be a brilliant game I think.
"Brentford played the night after us so that might be a factor. I was buzzing watching them – and I really enjoyed their performance against Derby the other week too.
"I watched wide-angled footage to see their shape, structure and patterns and I have to congratulate them.
"Someone has clearly taken a decision, like Swansea did, to play a certain way and they're sticking to it.
"I'm pleased for them because I used to play for them, but I want to stop them tomorrow."
The Lions go into the game buoyed by their late equaliser with ten men in a frenzied draw with Blackburn.
"I think our fans can see what we're trying to do and they're appreciating the lads' effort," Holloway added.
"We're almost good enough to compete with the very best in the division.
"At Watford the lads were arguing with the referee and on Tuesday it was the bench and I got sent off. I apologise to our fans for that.
"Somewhere along the line we'll get a happy medium of the lads not arguing, the bench not arguing and we'll get some fair decisions. Then life will be tickety-boo.
"But from my point of view, I want more of the same – from the players and fans. Apart from not getting all three points, which we deserved, it was a fantastic night at The Den."
